Design And Implementation Of Multimedia Playback System For Household Network Based On Virtual PC

With the development of computer technology,the Internet equipment growth is fast,and in recent years,people's living standards are increasing,and the purchasing power of family users is becoming stronger and stronger,intelligent devices in the home network gradually increased,while the family user demand for multimedia entertainment is more and more high,the traditional solution is do not keep up with the development of the times,it is difficult to meet the requirements of the people.On the other hand,with the development of virtualization technology and the progress of the Internet,cloud computing technology has become increasingly mature,cloud computing,intelligent Home Furnishing,internet of things and other new technologies are gradually entering into the ordinary home users,to provide external support is very good for the family of multimedia applications.In this context,the traditional family multimedia technology has not been able to meet the needs of users,and users need new solutions.This scheme can connect cloud devices on one side,and connect home intelligent devices on the other side,and provide simple and reliable multimedia services for users through network transmission.Under view of this trend of development,this thesis puts forward a home network multimedia playback system based on virtual PC.Through virtualization technology,cloud hosting is used to replace the traditional PC for the user,the user can apply to the management platform by using virtual PC;the mobile terminal in the home network as control devices,users connect virtual PC and home display device through the mobile terminal,browse the resources on the Virtual PC,and through the control function,will multimedia,virtual PC game application resource display in the family shows that the use of equipment;through the establishment of the network in the local area,such as community environment,we can realize the close communication between virtual PC and home users,and with bandwidth management system to ensure the quality of network service.This thesis first introduces the background and significance of the subject,and describes the status of the research at home and abroad.Then we analyze the mainstream virtualization technology and make a detailed comparison,and finally choose Xenserver as a virtualization solution.We also focus on the analysis of the traditional home multimedia protocol DLNA,and illustrate its implementation principle and point out its shortcomings.Then the function analysis and network analysis of the system are carried out,and the function points that the system needs to be realized are put forward.Then the module is designed for the function required,and the program is implemented.Finally,the test environment was built,and the system function and performance were tested respectively.The test results show that the system's functions are comprehensive,and the system performance is satisfied.It realizes the combination of home network multimedia and virtual PC,and meets the needs of family users in the new era.
